Stoyan has been coach for our young kids for last 5 years in Tampa. He is an engineer tuned to full time professional coach, He pays very close attention to kids. Stoyan really thought how a good coach can make difference. He gradually ramps up tennis skills with kids, he is very helpful to tune-up my kids for USTA tournaments, he sets high standards and drive kids toward to it. Time permitting, he occasionally visits the tournament places while my kids playing at match, offered while playing and after play, prepared them for next match. Additionally, he also offered nutritional supplement tips on, before play, while play and after play. Beyond coaching, he personally connects well with kids, motivates them to perform well. My kids and I love him so much. I would highly recommend Stoyan to anyone, specifically, my lesson learned is(from elder kid), always starting with a good coach makes a big difference!!!
